Title: Mercury-cadmium non-added manganese dry battery
Inventor: MURAKAMI HAJIME
IPC: H01M4/62
Filed: 1994-04-11
Abstract: PURPOSE:To stabilize a battery open circuit voltage immediately after constitution even if a quantity of zinc contained in a zinc alloy for a negative electrode can is large by adding metal salt into paste for a separator. CONSTITUTION:In a separator 2 for use in a mercury-cadmium non-added manganese dry battery, 0.01-0.1wt.% of aluminum, manganese, iron or cobalt is added in a form of salt into paste including mainly starch, a binder and a solvent. 0.01-0.5wt.% of sodium is added in a form of sodium salt into the paste including mainly starch, a binder and a solvent. Consequently, addition of metal into the paste of the separator increases a swelling speed of the starch so as to shorten a potential stabilizing time between manganese dioxide and zinc immediately after the constitution of the battery.

Title: High pressure electric discharge lamp
Inventor: SUZUKI RIYOU
IPC: H01J61/56
Filed: 1980-05-29
Abstract: PURPOSE:To emit light from a light emitting body immediately after an electric discharge lamp is turned off, by connecting a thermally operated switch, closed for the whole body at equal temperature and opened when partially heated by a heater, and the light emitting body in series. CONSTITUTION:A thermally operated switch 14 comprises the first thermally operated element 16 and the second thermally operated element 17 and opens a contact 19 when the second thermally operated element 17 is heated by a heater 15 connected in series to a luminous tube 1. When the luminous tube 1 is in a stable state of lighting, heat generation of the heater 15 causes the contact 19 to be as left in an open state. If the luminous tube 1 is turned off, the heat generation of the heater 15 being stopped causes the first thermally operated element 16 and the second thermally operated element 17 to be at equal temperature, then the contact 19 is closed to electrically conduct a filament 5 thus the filament 5 emits light. When the luminous tube 1 is again lighted, the heater 15 is again heated then the contact 19 is opened to cease emission of light of the filament 5.

Title: Detection circuit for repetitive image and image coder
Inventor: UEDA MOTOHARU
IPC: H04N19/00
Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To conduct excellent coding processing by detecting a repeated field in an excellent way so as to minimize visual deterioration thereby reducing redundancy sufficiently. SOLUTION: A moving/still image discrimination circuit 154 discriminates that a field is not a repeated field when an integral vector amount is more than a prescribed threshold value. In the case that the integral vector amount is not more than the threshold value, the circuit 154 discriminates the field to be a repeat field for the time being and references the presence of a motion recognition signal by a very small motion detection circuit 152. When a motion recognition signal is in existence, it is possible that a maximum level of noise is higher than an average level of the video signal and an impulse noise is in existence or the video signal is locally superimposed. Thus, the discrimination above is corrected and the field is processed not to be the repeated field.  In the case that the integral vector amount is not more than a threshold value and no motion recognition signal is in existence, the field is discriminated to be the repeated field.

Filed: 1984-04-13
Abstract: PURPOSE:To reduce leakage currents by forming a buried layer by diffusing an impurity to the upper section of a blocking layer previously shaped in thick size, constituting a p-n junction by a diffusion between the buried layer and the blocking layer and constituting a p-n junction between the buried layer and a clad layer. CONSTITUTION:A p type InP blocking layer 6 and an InGaAsP cap layer 8 are buried through an epitaxial method in succession. Since the blocking layer 6 is thick, an epitaxial growth layer is shaped positively extending over the whole region on a buffer layer 2, and a non-growth section such a pin holes is not generated. An impurity is diffused to a wafer to form a buried layer 7. The layer 7 is diffused into the blocking layer 6 because the impurity Te is diffused while using a mask 15 as a mask for a diffusion. A p-n junction through the diffusion in a clad layer 4 and a cap layer 5 is shaped, and the p-n junction stable in a crystallographic manner is obtained. Since the blocking layer 6, the buried layer 7 and the p-n junction also function as a p-n junction by the diffusion similarly, the p-n junction stable in the crystallographic manner is acquired.

IPC: H01L21/268
Filed: 1979-06-11
Abstract: PURPOSE:To perform efficient activation and attain good ohmic connection, by injecting ions into the surface of a semiconductor substrate to make an impurity layer, providing a wiring of Mo or the like and irradiating the reverse side with CO2 laser light or the like to simultaneously treat the impurity layer and the Mo film with heat. CONSTITUTION:Ions are injected into an Si substrate 3 to add an impurity 2. An Mo film 1 is coated. The reverse side of the substrate is irradiated with CO2 laser light 4 which almost penetrates the Si substrate. The energy of the light is absorbed near the boundary 5 between the Mo and the Si to activate the added atoms and treat the Mo film with heat. According to this method, only the impurity layer absorbs the energy of the light and the activation ratio is almost 100%. The Mo is well treated with heat near the boundary on the Si and unlikely to be affected by an atmosphere during the treatment. Therefore, good ohmic connection is attained. Mo and W are advantageous because their melting points are high and they are therefore not sublimed or evaporated.

Abstract: PROBLEM TO BE SOLVED: To protect the shoes of a passenger moving a slanting passage and a shopping cart moving near the getting on/off place by setting the external force to be detected of the second safety device disposed at the horizontal passage of a step at a smaller value than that of a first safety device. SOLUTION: The mounting intervals ha, hb of both reinforcing bodies of a first safety device 11 disposed at a slanting passage and a second safety device 13 disposed at a horizontal passage and gaps ga, gb thereof between the safety devices and a skirt guard 7 satisfy the relations of ha<hb, ga<gb. The second safety device 13 whose gap is small and easily detected because the mounting interval is larger and the skirt guard 7 is apt to deflect is used for detecting small external force and the first safety device is used for detecting large external force. The safety device responds to large external force produced when a hard shoe is pinched and resists detecting that a passenger kicks the skirt guard 7.  The second safety device is disposed at the higher position where the shoes are not pinched and it is hard to kick the skirt guard 7 and detects small external force and responds to a collisions of a shopping cart.

Filed: 1982-04-30
Abstract: PURPOSE:To improve overall durability including corrosion resistance, travelability and head clogging in connection with a magnetic recording medium of a ferromagnetic thin metallic film type, by providing an adsorbent layer for a rust inhibitor on a thin metallic film and providing a layer contg. an org. lubricant on one surface where the substrate remains. CONSTITUTION:In the figure, 1 is a substrate, 2 is a ferromagnetic thin metallic film, 3 is an adsorbent layer for a rust inhibitor and 4 is a lubricant layer. Part of the lubricant in the layer 4 is transferred onto the layer 3 by such constitution in the stage of winding a magnetic recording medium; therefore, the coefft. of friction on the magnetic surface side is decreased by the effect of the lubricant transferred in the stage of traveling of the magnetic recording medium, whereby the traveling stability and durability are improved. Rust inhibitors used for general metals are usable as the rust inhibitor to form the adsorbent layer for the rust inhibitor for the ferromagnetic thin metallic film wherein oxygen is not particularly contained. Fatty acid, fatty acid ester, fatty acid amide, metallic soap, aliphatic alcohol, paraffin, silicone, fluorine surface activating agents, etc. are usable for the lubricant.
